Quick startDrag(); question

startDrag(); seems to stop dragging once the mouse leaves the stage. Is there a way to set it to still drag when off the stage. The exhaustive search I’ve tried only says things about capture the event for the mouse leaving the stage, not continue any dragging or animation, etc.

In more detail, I have a “flashlight” type sprite that covers everything with black, and allows the user to see a small circle of stage. The center of the circle is where the mouse is. When the mouse goes over the edge, half of the circle (or more depending on how fast the mouse moved) is still visible. I need it to at least move off stage completely.
